Lambda is good for bursty, typically low activity applications, where it just wouldn't make sense to have EC2 instances running 24x7. There about some line-of-business app that gets a couple of requests every minute or so. Maybe once a quarter there will be a spike in usage. Lambda scales up and just handles it. If requests execute in 50ms (unlikely!) or 500ms, it just doesn't matter.
